We have developed cationic iron(IV) corrole-catalyzed formal hetero-Diels–Alder reaction of aldehydes with dienes, which opens the way for divergent synthesis of pyrans. The potential utility of the catalyst was also demonstrated by carrying out cycloaddition of α,β-unsaturated aldehyde with a diene to give pyran selectively. Furthermore, the catalytic reactivity of iron corrole complex on the cycloaddition was determined by comparing that of iron porphyrin complex.
我们开发了一种阳离子
铁(IV) corrole 催化的醛与二烯的正式杂-Diels-Alder 反应,这为
吡喃的多样性合成开辟了道路。催化剂的潜在应用价值也通过 α,β-不饱和醛与二烯的环加成反应得到选择性
吡喃的生成得以证明。此外,通过比较
铁 porphyrin 配合体在环加成反应中的催化活性,确定了
铁 corrole 配合体的催化反应活性。
